Nissan Armada 2025-2026 Service and Repair Manual: Adjustment
PINION GEAR HEIGHT
If the hypoid gear set has been replaced, select the pinion height adjusting washer.
Use the formula below to calculate pinion height adjusting washer thickness.
| Washer selection equation: | |||
| T = T0 + (t1− t2) | |||
| T: | Correct washer thickness | ||
| T0: | Removed washer thickness | ||
| t1: | Old drive pinion head letter “H × 0.01” (“H”: machined tolerance 1/100 mm × 100) | ||
| t2: | New drive pinion head letter “H × 0.01” (“H”: machined tolerance 1/100 mm × 100) | ||
| Example: | |||
| T = 3.21 + [(2 × 0.01) − (−1 × 0.01)] = 3.24 | |||
| T0: | 3.21 | ||
| t1: | +2 | ||
| t2: | −1 | ||
Select the proper pinion height adjusting washer. For selecting adjusting washer, refer to the latest parts information.
CAUTION:
If unable to find a washer of desired thickness, use a washer with thickness closest to the calculated value.
| Example: | ||
| Calculated value... T = 3.22 mm | ||
| Used washer... T = 3.21 mm | ||
COMPANION FLANGE RUNOUT
Fit a dial indicator onto the companion flange face (inner side of the propeller shaft mounting bolt holes).
Rotate companion flange to check for runout.
| Companion flange face runout | : Refer to Companion Flange Runout. |
Fit a test indicator to the inner side of companion flange (socket diameter).
Rotate companion flange to check for runout.
| Inner side of the companion flange runout | : Refer to Companion Flange Runout. |
If the runout value is outside the runout limit, follow the procedure below to adjust.Check for runout while changing the phase between companion flange and drive pinion by 90° step, and search for the position where the runout is the minimum. If the runout value is still outside of the limit after the phase has been changed, possible cause will be an assembly malfunction of drive pinion and pinion bearing and malfunction of pinion bearing. Check for these items and repair if necessary. If the runout value is still outside of the limit after the check and repair, replace companion flange.
